# SOAP API Reference

> **Note**
>
> This page describes functionality for the older eSignature SOAP API. See [eSignature REST API reference](/docs/esign-rest-api/reference) for more information on this topic in the more actively-supported eSignature REST API documentation.

The SOAP Developer’s Guide provides information about the Docusign SOAP [Service API](/docs/esign-soap-api/esign101/api-info) and [Account Management Service API](/docs/esign-soap-api/reference/account-management-service-api).

This guide also includes information on [Docusign security requirements and API call limits](/docs/esign-soap-api/esign101/security), [authentication](/docs/esign-soap-api/esign101/auth), and using [Web Services Description Language (WSDL)](/docs/esign-soap-api/esign101/wsdls) to implement the API.
